Is this normal hcg rise?

Hi my name is Alda and i' currently 6w1d pregnant and I'm worried sick about having a misscarige so I've been taking tests every morning and every other evening just to make sure my hcg levels are rising! The green sticks are FMU and the are always the same, is that normal? The other test seem too be getting darker though. I'm so confused so I just wanted a second oppinion! ❤️
